Which of the following best describes the effect of an increase in hemoglobin concentration on oxygen delivery to tissues?
A
Increased oxygen delivery due to increased oxygen-carrying capacity
B
Decreased oxygen delivery due to increased blood viscosity
✓
C
No change in oxygen delivery as the increase in hemoglobin is compensated by a decrease in cardiac output
D
Increased oxygen delivery only in tissues with high oxygen demand
Explanation
An increase in hemoglobin concentration can lead to increased blood viscosity, which can decrease blood flow and oxygen delivery to tissues.
